This paper extends Kiefer, Vogelsang, and Bunzel (2000) and Kiefer and Vogelsang (2002b) to propose a class of over-identifying restrictions (OIR) tests that are robust to heteroskedasticity and serial correlations of unknown form. These OIR tests do not require consistent estimation of the...

Research from the United States shows that gaps in early cognitive and non-cognitive ability appear early in the life cycle. Little is known about this important question for developing countries. This paper provides new evidence of sharp differences in cognitive development by socioeconomic...

We empirically analyze the trend characteristics of per capita CO2 emissions in OECD countries from 1971 to 2009. We use a statistically robust procedure, which is valid regardless of whether per capita CO2 emissions are trend stationary or contain a stochastic trend, to test for the presence of...

Using cross-country data, this paper estimates the impact of the 2007 financial shock on countries’ macroeconomic developments conditional on national financial regulations before the crisis. For this purpose, the "financial reform index" developed by Abiad et al. (A New Database of Financial...

This paper provides doubly robust estimators for treatment effect parameters which are defined in multivalued treatment effect framework. We apply this method on a unique data set of British Cohort Study (BCS) to estimate returns to different levels of schooling. Average returns are estimated...
